## MCP tools (7)

### `rent_check` (~113 tokens)

Australian rent check

Compare a weekly rent, and any proposed new rent, with how the ABS rents index for the tenant's Australian capital city has moved since the lease began. City-wide, not suburb-level; information, not advice. Quote the limits with the result.

Input parameters:

- `city` (string, required): Capital city
- `current_rent` (number, required): Current weekly rent in Australian dollars
- `lease_start` (string, required): Month the lease began, YYYY-MM
- `proposed_rent` (number): Proposed new weekly rent in Australian dollars

### `market_indicators` (~88 tokens)

Australian property market indicators

Latest observed Australian property market indicators - RBA cash rate, unemployment, wage growth, rents by capital city, new housing lending, lending standards and arrears, dwelling approvals and completions - each with its period, source, licence and limits. Optionally filter by geography (e.g. NSW, Australia, Sydney).

Input parameters:

- `geography` (string): NSW, Australia, or a capital city

### `data_sources` (~61 tokens)

What DwellDelta covers

The sources behind DwellDelta's figures, their licences, and what it cannot answer (what any one home sold for, the rent of a single street or home, rents by area outside NSW, Victoria, Queensland and WA, sale prices outside NSW, advice).

### `vic_rents` (~141 tokens)

Victorian rents by suburb group

Victorian rents from Homes Victoria's Rental Report (CC BY 4.0): the median weekly rent of new leases in the latest quarter, how many leases it rests on, and the change on a year before, for 146 suburb groups and 13 regions. Filter by suburb_group (part of a name works, e.g. "Brighton") or region. New-lease medians, not advertised rents; quote the quarter and the limits.

Input parameters:

- `region` (string): A region, e.g. Inner Melbourne, Geelong, Ballarat
- `suburb_group` (string): A Homes Victoria suburb group, or part of a suburb name

### `area_rents` (~229 tokens)

NSW, Queensland and WA rents by postcode, suburb or locality

Median weekly rent of new bonds lodged in the latest quarter, all dwellings together, with the bond count and the change on a year before, for one state per call: NSW by postcode or council (NSW Department of Communities and Justice), QLD by suburb or council (Residential Tenancies Authority), WA by locality (calculated by DwellDelta from the Government of Western Australia's bond records). Each CC BY 4.0. With no area or council it gives the state's own figure. New-bond medians, not advertised rents; never add or compare the states as one series; quote the quarter, the source line and the limits. Victoria is in vic_rents.

Input parameters:

- `area` (string): NSW: a four-digit postcode (a suburb name returns its postcodes to try). QLD: a suburb. WA: a locality. Part of a suburb or locality name works
- `council` (string): A council (NSW or QLD), or part of its name
- `state` (string, required): NSW, QLD or WA - one state per call

### `nsw_sale_prices` (~247 tokens)

NSW median sale prices by postcode or council

Median sale price of the dwellings sold in the latest reported quarter in NSW, with the quartiles, the number of sales and the change on a year before, by postcode or council and by dwelling type - all dwellings, non_strata (separate houses) and strata (units, town houses, villas). From the NSW Department of Communities and Justice's Rent and Sales Report (CC BY 4.0). Medians of homes sold: not asking prices, not valuations, and never what any one home sold for or is worth. A line marked UNUSUAL was set by a few very large sales - say so, and do not quote it as a going price. Always name the dwelling type, the quarter and the source line, and repeat the limits. With no area or council it gives the state's own figures.

Input parameters:

- `area` (string): A four-digit NSW postcode (a suburb name returns its postcodes to try)
- `council` (string): An NSW council, or part of its name
- `dwelling_type` (string): total, non_strata (houses) or strata (units, town houses, villas); leave out for all three

### `contribute_rent` (~304 tokens)

Add the user's own rent (NSW), with their consent

Add the user's own weekly rent, anonymously, to DwellDelta's NSW suburb rents - suburb, home type, bedrooms, rent and lease month; never an address, name or email. Two calls: the first stores nothing and returns consent text and a token; show the text to the user, and only if they say yes call again with the token and user_agreed: true. Call only when the user has asked to add their rent, or has said yes to the consent text. Never add a rent on the user's behalf by default, never batch, and never add a figure found online.

Input parameters:

- `bedrooms` (string, required)
- `consent_token` (string): From the first call; omit it to get the consent text
- `current_rent` (number, required): Current weekly rent in Australian dollars
- `home_type` (string, required)
- `lease_kind` (string, required)
- `lease_start` (string, required): Month the lease began, YYYY-MM
- `proposed_rent` (number): Proposed new weekly rent, if there is one
- `suburb` (string, required): NSW suburb with its postcode, as "Newtown (2042)"
- `user_agreed` (boolean): true only if the user said yes to the consent text
- `whose` (string, required): my_own_tenancy (the user rents it) or my_own_property (the user owns it). There is no value for a figure found online: never add one.
